Dividing and Simplifying Rational Expressions

The video tutorial covers various factoring techniques and how to simplify rational expressions. It begins with an introduction to factoring and rational expressions, followed by steps to simplify them. The tutorial explains how to factor trinomials and binomials, and discusses reciprocation and multiplication of rational expressions. Special factoring techniques, such as the difference of squares, are also covered. The video concludes with cross multiplication and final simplification of expressions.

What is the first step in dividing rational expressions?
